I have two MC's on stage,
MCmenu is a button array,
MCtext is a collection of text with frame labels. It's labeled as MCtext
The menu buttons tell MCtext to play the frame label as the button clicked. This *used to work*, but Flash was laggy as hell so I updated it. Now the same code returns #1009: Cannot access a property or method of a null object reference. at MCmenu/itemClicked()
Code:
function itemClicked(butn:Event):void {
parent.MCtext.gotoAndPlay(SomeArray[butn.currentTarget.label);
}
I've tried just using a frame number, but still the same #1009
I've tried the Script Assist to target the MC on the stage:
using root.MCtext... still the same #1009
using this.MCtext... returns a #1010

I am presuming this is because the image hasn't finished reading the png file off the disk yet. What event can I monitor to know when it's width and height will have the right values? The 'Complete' event only seems to work for DOWNLOADED images. The 'Render' event happens EVERY FRAME. The (undocumented?) 'sourceChanged', happens as soon as source changes, and has the same problem! What event do I watch that will let me know when the image's width and height properties will have valid values? Or is there some Synchronous version of I.source='xxx.png', that I don't know about?
P.S. Yes, I know I shouldn't use "C:" in an Air Program. This was just for illustrative purposes, so that you won't suggest I use "Complete", which never even seems to fire when the file indicated by source is local.

Is it possible to make text content for a site in Flash be changed/updated by someone without having to take the route of Flash? Like I have a text file in notepad, or Word and the text will automatically appear in the swf file?

I've created a flash card class in ActionScript that uses a tween to flip the card over the y-axis (i.e., by using rotationX). I also use the bounds property of startDrag so that, when you drag it, its movement is locked on the x-axis. (There's also a method for switching between dragging and flipping, but since that's not broken, there's no need to discuss it further).
Here's my problem. If I haven't yet flipped the flash card over, the card drags fine. If I flip the card over and don't use bounds in startDrag, it works fine. But if the bounds property is set and then I try and drag the flash card after it's been flipped, the movement goes all haywire. It basically jumps back and forth between the two ends of the bounds' rectangle.
Is there any way you can think of to solve this problem? Alternatively, is there any way to use sprites to limit movement? For example, would it be possible to place a pair of one-pixel-thick horizontal lines on the top and bottom side of the flash card, set their alpha to zero, and somehow stop the flash card from moving past the lines?

I have an AS3 program that calls a function multiple times. The function must return multiple variables, so I created a class for the function to declare an object containing all of these variables. For example, here's my class:
package
{
public class PER
{
[Code].....
Let's say the calling program calls the function, which returns the variables into data_set1 (where data_set1 depends on input variables arg1, arg2, arg3) using:
var data_set1:PER = function_name(arg1, arg2, arg3);
The calling program does some stuff, then calls the function again, but returns the variables into a new variable name, data_set2:
var data_set2:PER = function_name(arg4, arg5, arg6);
My intention is that data_set1 and data_set2 are different (e.g. not linked together).
My question is, given that arrays are passed by reference, will data_set1 be modified to agree with data_set2 upon the 2nd function call? Why or why not?

Reading a book i stumbled on this example:
Here is the class:
package com.learningactionscript3.loading {
import flash.display.Loader;
import flash.display.LoaderInfo;
[Code]....
What I deduce from this example is that the swfLoader.contentLoaderInfo and _ldrInfo = this.contentLoaderInfo refer to the same object in the same memory location. So you may think: "well the last added event will overwrite the first one (the internally one added). But it doesn't. The two event listeners will respond sequentially. First the internal listener and then the external listener.

I have 2 swf that will be loaded on a website. One suppose to generate a bytearray and being passed over to another swf.
The problem is that when I save the bytearray to a SharedObject in user's local file, the second swf doesn't get the updated variable value from the first swf.
I've set the second swf to retrieve the value every one second and it don't get updated until I reload the page.
I flushed and close the connection to make sure the data is saved on the local path and that is not helping as well.
I also considered using LocalConnection as well but there is a bug in flash player for mac that stopping it to work between swfs on mac. Left me no choice but to use SharedObject for my project.

I'm trying to detect if a shared object's value has changed. Is there a way to do this? I'm using setProperty and it works fine but I need to change info the info has changed. I have tried event.changeList but it just shoots out [Objects] without giving me values. Can't it tell me a boolean to see if it has changed?

I'm trying to convert an MXML component to an ActionScript Class. The component consists of a Form with a TextInput, TextArea, and two buttons - Save and Cancel, and a Validator for the TextInput, and other logic to handle events that occur. This component is currently extended by several other components. Now, in the MXML component binding the TextInput text property to a property in an Object was very easy:
<mx:TextInput text="{_itemToEdit.name}" />
But in ActionScript, I'm creating the TextInput and setting the text property before the Object is set, and the TextInput is not being updated:
public var itemToEdit:Object = {};
private var nameInput:TextInput = new TextInput();
public function MyClass() {
nameInput.text = itemToEdit.name;
}
How can I make sure that the TextInput text property is bound to the specified property in the Object?

I'm trying to assemble a header object for an api request. One of the headers is 'Content-Type'. The hyphen is causing a compile error. Flex is giving me:
1050 - Cannot assign to a non-reference value.
I find it spiteful that they enjoy the use of a hyphen in the error message while I hang my head and come here for answers.

I have a dynamic class that I have created
public dynamic class SiteZoneFileUploadVO
{
public var destination:String = "sitezone";[code]...........
when I try to iterate over this object's property names it only iterates the dynamically added properties.
parameters.dynVar= "value";
for(var name:String in parameters)
{
Even though the object has all the properties equal to a value (ive checked this in the debugger) the only property name that will be traced is dynVar.How can I iterate over all the property names and not just the dynamically added ones?

I need to create variable object property names for use with the data grid component.
This works: data = new Object(); data.some_name = "the data";
But this does not: data = new Object(); colName = "some_name"; data[colName] = "the data";

I'm writing a sort of "dynamic gallery" in flash. The problem is that a child of the gallery can be resized in runtime, and then I have to rearrange the gallery.
Now, of course, I can't overload the gallery items, since it's a display object which
is unpredictable. and even if I could force overloading on the items, how will I be notified if, let's say, an animation started, something move, and the item got bigger Is there some sort of Event for a display object which is dispatched on ANY kind of resize ??
My dumb solution was to go through all the gallery's items and rearrange them every given milliseconds, and now I feel so dirty and I need to confess my sins.

I am using shared object to share data between two users. First user connect to shared object and set some value in shared object. Please consider that second user has not connected with the shared object yet.Now when second user connects to the server and try to get that property set by first user, he could get shared object but could not get properties of Shared object set by first user. I observed few times that Second user can get these properties within "Sync" event between two users. But I would like to get these values for Second user in any stage (i.e. in load event etc.). Whenever Second user tries to get the property of Shared object, the object will reset the actual property value and then return reset value.
1) Is there any way to get all the properties of shared object before sync event called, as I want to get it immediately when second user connect to the application and perform next task based on the values stored in shared object.
2) Is it possible for second user to check whether any property has been set by first user? So that second user can use the property instead of reset it.
